Question
A steel column of rectangular section () and length is simply supported at both ends. Assuming modulus of elasticity, for steel, the critical axial load (in kN) is ____ (correct to two decimal places).
Correct answer
1 to 1.2
Solution
The critical axial load for a simply supported column (Euler's buckling load) is given by:Given data:
- Section dimensions: ,
- Modulus of elasticity:
- Length:
